problems while playing on mobile

Hi,not sure this is the right place to post this.Since 2 or 3 days i've experienced big problems in playing Carcassone on my mobile. All tiles are somehow "blurred", meaning that the pictures are moving and is not possible to clearly understand the scenario, the shape of the cities, etc. It has never happened before. I'm using an iphone 6, 10.2.Is anyone else experiencing the same issue?
